Disable reclaim and resource sliders if the respective generator is set to random

[BlackYps]

Is your feature request related to a problem?

People use the reclaim sliders (for example setting it to low) while keeping the prop generator at random and are then frustrated when a high reclaim map comes out because a prop generator got selected that always produces a lot of reclaim.

Describe the solution you'd like

We should disable the sliders when the respective generator is set to random.

Describe alternatives you've considered

ALternatively having the slider restrict which generators can be chosen is the behaviour that we just went away from and it is too opaque for the user.
